Knowledge representation of product lifecycle management demand flow chain in garment sector

In order to meet customers demand on garments,the knowledge representation of product lifecycle management demand(PLM) flow chain in the garment sector is put forward.Systematic knowledge is used to describe the cooperative knowledge structure,the formation of cooperative knowledge representation of PLM demand flow chain is analyzed in PLM demand flow chain,and the cooperative knowledge concerning the whole demand flow chain is defined.Finally,the prototype system of PLM cooperative knowledge representation system—KESFCRFN is developed.The system′s architecture,modeling technology and operation process are studied.The results reveal that the applying knowledge representation to describe the demand cooperation in PLM demand flow chain has optimized the demand structure and resources for systematic implementation and improved the competitive power of garment enterprises.
